seaweedFS/weed/command/scaffold/filer.toml
Chris Lu 5d53edb93b Optimize database connection pool settings for MySQL and PostgreSQL (#7645) 
- Reduce connection_max_idle from 100 to 10 (PostgreSQL) and from 2 to 10 (MySQL)
- Reduce connection_max_open from 100 to 50 for all database stores
- Set connection_max_lifetime_seconds to 300 (5 minutes) to force connection recycling

This prevents 'cannot assign requested address' errors under high load by:
1. Limiting the number of concurrent connections to reduce ephemeral port usage
2. Forcing connection recycling to prevent stale connections and port exhaustion
3. Reducing idle connections to minimize resource consumption

Fixes #6887

#
# 1. Add a name following the store type separated by a dot ".". E.g., cassandra2.tmp
# 2. Add a location configuration. E.g., location = "/tmp/"
# 3. Copy and customize all other configurations.
# Make sure they are not the same if using the same store type!
